of the barrel. Every such change or modification, for better or worse, 

 must be expected to add to, or lessen, the cost accordingly. 



Appliances. — Aside from selecting a good pump, you must also decide 

 how much liose you want, how long an extension pipe will be needed, and 

 the kind of nozzle. You must also state that you want whatever connec- 

 tions, washers, etc., will be needed to put the entire outfit in condition 

 for use. It will also be an advantage to have a stopcock at base of the 

 extension pipe, so the spray can be cut off at any moment to prevent 

 waste. All these little appliances add more or less to the cost, but a suit- 

 able arrangement of them is the very making of a satisfactory outfit. 



For bucket, knapsack and compressed-air pumps, from six to ten feet 

 of extra hose is enough, but for barrel pumps we advise at least fifteen 

 feet of extra hose. The extension pipe should be six to ten feet long, 

 according to the size of trees. We prefer a nozzle Avhich throws a cone- 

 shaped spray and which is set at an angle so as to permit greater range 

 of work. Many of these details the grower must settle for himself by a 

 study of the catalogues, or from individual experience. 



MANUFACTURERS AND DEALERS IN SPRAY PUMPS. 



It will be well to write to any or all of the following firms and ask 

 for their illustrated catalogues and price-lists of spraying outfits, study 

 them carefully, figure on the length of hose, extension pipe, etc., before 

 placing your order.

SPRAYING DEMONSTRATIONS— Proof of Value of Spraying. 



For several years the Divisions of Entomology and Horticulture of 

 the State Department of Agriculture have conducted jointly a series of 

 public demonstrations in the spraying and pruning of orchard trees — 

 especially apples. This account has to do only with the spraying, which 

 is done by the Division of Entomology. 



These demonstrations have now been repeated in so many years, and 

 in every section of the State (east, middle, and west), until the general 

 results cannot possibly be a matter of chance, and these results prove 

 beyond dispute that the spraying of apples is profitable in all sections of 

 the State.
